Thank you for the quick reply. You were right I had downloaded the source instead of the dist. I ran: mvn package && mvn assembly:single –N as per the Accumulo README. I'm not getting the exception anymore but now I can't get it to connect for some reason. Again, Hadoop and Zookeeper are running fine and this is the error that I get after $ACCUMULO/bin/accumulo init

Either you meant to download the dist instead of the src, or you did not build the src. Make sure you downloaded the src, or run maven package (requires maven to be installed).
